The External Power Cartridge and Charger from AirSep is compatible with the Focus and Freestyle 3 and Freestyle 5 portable oxygen concentrators. This is one of the options you have for supplemental battery power with these models. Here is the information about this great supplemental battery kit.
Just when you thought it could get any better for adding extra battery life to your small AirSep portable oxygen concentrators, along comes the AirSep External Battery and its Charger. Just one external battery cartridge only weighs 1 lb, and can hold as much as 3.5 hours of battery life, depending on which AirSep concentrator you are using, and at which setting. On the AirSep Focus on the setting of 2, you can enjoy 3.5 more hours of complete mobility. Not only do you get more battery life, but the external charger makes it possible to charge 2 batteries at once, separately from your Focus or Freestyle 3 or Freestyle 5. This is extremely convenient for travel, or if you need your oxygen therapy for many hours out of the day.
The only bad thing about this product is, that it only comes with 1 battery with the charger, instead of the 2 that it can accommodate.
The Bottom Line
A great option for adding more battery life to your Focus or Freestyle. The price is also great for one battery along with the charger. It takes 5 hours to charge one battery, but since you are able to charge 2 at once (if you buy another one) this makes it easier to leave the house with as much battery power as possible, so you won’t need to worry about having to stop to charge somewhere. Overall, this is the accessory to get if you plan on going on a long trip, since you will need to leave with a lot of battery life at once.
